Here is what nobody tells you. This quest requires HOURS OF WALKING!!! There is no chocobo to use in the past. You don't just "go" to windurst waters [s] and click on door. You first have to unlock one of the 3 main maws, Batallia Downs(H-5) Rolanberry Fields (H-6) Sauromugue Champaign (K-9). If you end up at Sauromugue after clicking on a MAW make sure to travel back into Rolanberry to unlock that maw from the past or you will have to go past gate #3 in garliage to get back to Sauromugue maw. Lets just say you start in Rolanberry [s] Here is how to get to windy which nobody tells you. Rollanberry [s]-> Sauromugue Champaign (S)-> Meriphataud Mountains (S)-> The way is blocked if you want to go south from here so you have to travel into Fort Karugo-Narugo [S] which is found at C-11, D-6, D-8, D-9, L-6, K-11 in Meriphataud Mountains (S) South end of the Fort exits into West Sarutabaruta. You can either do quest for the fort map in Crawlers nest or go here -> http://wiki.ffxiclopedia.org/wiki/Fort_Karugo-Narugo_%28S%29/Maps Once you get to Windy make sure to click on the Maw there at West Sarutabaruta (S) (H-9) so you don't have to walk here again in the past. <--I wish I had this info when I started.

I started this quest not really knowing what Retrace did. I didn't bother looking at the ungodly AH prices, or anything like that. All I knew was I'm a lvl 75 BLM, and I wanted the latest in BLM magics. Low, and behold; I finally got the damn scroll, used it, casted it, and it took me to the HP in windy waters {s}. I finally took the time to look at the in-game spell description, and that's when I found out it takes you to whichever nation you're serving under for campaign. How cool is that?

Click on the Rhinostery door at J-9 in the southern part of Windurst Waters (S) to receive a cut-scene.

Go to Giddeus in the present with a Mythril Beastcoin. On the first map there is a patch of grass at G-8 to drop down, go north and visit the Storage Room at G-6 on lower map. You will find Quu Bokye, a Yagudo NPC. Talk to him, and he asks for a Mythril Beastcoin he will give you Leather-bound Book key item when you trade the coin.

Go back to Windurst Waters (S) and return the Leather-bound Book to the Rhinostery door which triggers another cut scene with Yoran-Oran. Now go to the north side of Windurst Waters (S) and click on the door of the Optistery at F-8 for a cut scene with Yoran-Oran and Tosuka-Porika.

Now you gotta get a Lynx Pelt and a sheet of Vellum. Travel to Castle Oztroja (S) to G-8 and click on the ??? to obtain the Key Item Lynx Pelt.Yags are sight so wait for them to turn around. Time to head back.

Trade a sheet of Vellum to Door:Optistery for another cutscene. Vellum can be made with Leathercrafting, bought at AH, or you can go to Crawler's Nest (S) and trade 4 stacks of Rolanberrys at a time (you get more Vellum than you need but i sold them 15k a stack on Diabolos).

Wait one game day (no need to zone), then return to the Optistery for the final cutscene and a Retrace scroll as your reward.

Ok this is odd... Instead of asking for a mythril beastcoin he says "Books are good but silver beastcoins are better! Ack ack ack." And I try to trade a silver beastcoin to him (also tried mythril) and he doesn't do anything.
